I-POM (POLOXYTHTHTH) I-POLOXYTHTHTHTHTHTHTHTHTH LOROXYTHTHTHTHTHTHTH LOROXYTHTHTHTHTHTHTHTH LITE IGAMA IGAMA IGAMA IGAMA IGAMA IGAMA IGAMA LE-POMEXTHTHTHTHTH LICETHTHTH LORTETHTHTHTHTHTH Ifunyanwa yi-Polymerimbe yeForymermehyde njengezixhobo eziluhlaza. I-POM-H H (POLOXYMETHTHLE HOOPOPOLT) kunye ne-POM-K (POLOXYETHTHLE) ziiplasitiki zobunjineli bobunjineli obuphakathi kunye ne-crystallies ephezulu. Inezinto ezilungileyo zomzimba, oomatshini kunye neekhemikhali, ngakumbi ukumelana nokuchasana nokuchasana. I-POM yi-polymer ye-colymer engenamakhonkco esiphezulu, uxinzelelo oluphezulu kunye ne-crystallies ephezulu, kunye neepropathi ezigqibeleleyo. I-POM yinto enzima nengagungqiyo enomphezulu ogudileyo, ogcobileyo, ekhanyayo okanye emhlophe, kwaye inokusetyenziswa ixesha elide kuluhlu lobushushu lwe -4-100 ° C. Ukunganyangeki kwawo kunye nokuzithoba kuyapheka nako kunangaphambili bethayile, kwaye kuyachasana neoyile yeoyile kunye nokunganyangeki kwePeroxide. I-acid kakhulu kwi-acids, i-alkalis eyomeleleyo kunye ne-ultraviolet radiation.
Iipropathi zomzimba
I-Polyoxymethynene inamandla e-thensle ye-70MPA, ukungena kwamanzi asezantsi, uzinzo oluphakathi, kunye ne-gloss. Ezi ndawo zingcono kune-NYLOLO. I-Polyoxyylene yi-crink ye-crin ye-crin, enamandla kakhulu phakathi kwe-thermoplastic resistik. Inamandla aphezulu e-shirmas, ukugoba amandla, amandla okuxhaphake, kwaye ukunxiba ngokuchasene nokuchasana kunye neepropathi zombane. Ukusebenza kwe-POM: Inombolo yentsebenzo yexabiso le-Instal 1.43 Inyibiliki ye-175
Uluhlu lwesicelo
I-POM yiplastiki ye-crystalline enendawo yokunyibilika. Nje ukuba ifikelela kwindawo yokunyibilika, i-vicofity ye-viscosity ihla ngokukhawuleza. Xa iqondo lobushushu lidlula umda othile okanye inyibilike ishushu ixesha elide, iya kubangela ukungavisisani. I-Pom inezinto ezilungileyo ezibanzi. Yeyona inzima phakathi kwe-thermoplastics. Yenye yezinto zeplastiki ezathatyathwayo ezikufutshane nentsimbi. Amandla ayo angamathobeli, ukugoba amandla, amandla okudinwa, ukunxiba iipropathi zombane kwaye konke kulungile, kunokusetyenziswa ixesha elide phakathi kwe-degrees ezingama-100.
Iipropathi zeekhemikhali
Ngokwendlela eyahlukileyo ye-molecular ye-molecular, iPolyoxyythylene inokwahlulwa ibe yi-homopolymethymethymethymethymethymeene kunye neCopolymethylene. Okwangaphambili unoxinano oluphezulu, i-crystallivend, kunye nendawo yokunyibilika, kodwa inobushushu obungaphantsi komhlaba, ubushushu obuxineneyo (i-10 degrees), kunye nokuzinza kancinci kweasid; Le yokugqibela inexilongo eliphantsi, i-crystalliety, kunye nendawo yokunyibilika, kodwa inozinzo oluhle kakhulu, akukho lula ukubola, kwaye inobushushu obubanzi (i-50 degrees ngokubanzi). Iintsilelo zezi: I-SURRONION NGE-AID EID, UKUKHUSELEKA IXESHA LOKUGQIBELA, UKUZONWABISA NGOKUGQIBELA, UKUQHUTYWA KOKWENZA IXESHA LOKUGQIBELA KAKHULU, Isalathiso somhlaba seoksijini sisondele. Zisetyenziswa ngokubanzi kwishishini lemoto, izixhobo ze-elektroniki, izixhobo zoomatshini, njl.S. Itheyibhile yePropathi yePropathi yePropathi: Ukuxinana G / CM3 1.39

I-POM inomlinganiso ophantsi kakhulu wokuxazulula kunye nokuzinza kwejometri efanelekileyo, ngakumbi ilungele ukwenza iigiya kunye neebhere. Kuba ikwanokuchaswa kobushushu obuphezulu, ikwasetyenziswa kwizixhobo ze-Pipelit (i-valve yombhobho, i-valves, ipompo yezindlu), izixhobo zengca, njl. Njl.
Iimeko zeNkqubo
Unyango olomileyo: Ukuba loo nto igcinwe kwindawo eyomileyo, ihlala ingadingi yomiswe. Ubushushu bokunyibilika: I-190 ~ 230 ℃ yezixhobo ze-homollymer; I-190 ~ 210 ℃ yezixhobo zeCopolymer. Iqondo lobushushu: 80 ~ 105 ℃. Ukwenzela ukunciphisa i-shrinkage emva kokubumba, iqondo lobunganga liphezulu linokusetyenziswa. I-Ination Inxuwa: I-700 ~ 1200bar yenaliti Imbaleki nesango: naluphi na uhlobo lwesango kunokusetyenziswa. Ukuba i-Tunnel-Grednet yesango lisetyenziswa, kungcono ukusebenzisa uhlobo olufutshane. Kwizixhobo ze-homollymer, iimbaleki ezishushu ze-nozzle ziyacetyiswa. Kwizixhobo ze-copolymer, zombini iimbaleki ezishushu zangaphakathi kunye neembaleki ezishushu zangaphandle zinokusetyenziswa. I-POM yemichiza kunye neepropathi zomzimba zePolyxolo: I-Pom yimpahla enzima nelixineneyo enokunganyangeki kakuhle, uzinzo lwejometri kunye nokungaxhathisi bempembelelo nakumaqondo obushushu aphantsi. I-POM inazo zombini izixhobo ze-homopolymer kunye nezixhobo zeCopolymer. Izinto ze-homollymer zinolangazelelo olulungileyo kunye namandla okudinwa, kodwa akukho lula ukuyenza. Izixhobo ze-copolymer zinozinzo oluhle kunye neekhemikhali kwaye kulula ukuziqhubela phambili. Zombini izinto ze-homollymer kunye nezixhobo ze-copolymer zizixhobo zekristali kwaye akukho lula ukufunxa umswakama. Inqanaba eliphezulu le-crystallies ye-POM likhokelela kwireyithi ephezulu kakhulu, enokuba ngaphezulu kwe-2% ukuya kwi-3.5%. Kukho amaxabiso ahlukeneyo e-shrinkage kwizixhobo ezahlukeneyo ezongeziweyo.
Umahluko we-POM kukuba ubunzima kunye nobunzima bayo busondele kwintsimbi, kwaye ubushushu bayo obuphezulu kwaye banxibe ukuxhathisa. Ingasetyenziswa njengeenxalenye ezinjengeegiya.
